[Tex/LaTex] Newline in table cell possible

line-breakinglyxtables

I am trying to add linebreaks in my table cell but found that LyX doesn't allow me to. How can I insert a newline inside a table cell?

go into the menu of the tabular (right mouse click when cursor is inside the tabular) and then choose a width for the column. Then you can have linebreaks inside this cell with \newline or with an empty line for a new paragraph.
